Power Bank Prime Day Deals
The Nimble Champ has topped our Best Power Banks guide for a few years. The big option packs a hefty 20,000-mAh capacity, is smaller than a deck of cards, and can deliver 65 watts to charge two devices at once via USB-C ports on either end. We like the speckled color finishes and the bright lanyard loop, but what really sells these power banks is the 90 percent certified recycled plastic construction and fully biodegradable packaging. You get a 3.3-foot USB-C to USB-C cable in the box.
Want to charge smartphones, tablets, or laptops? The upgrade pick in our guide is all you need. This beast from Anker boasts a 25,000 mAh capacity, has three USB-C ports rated at 100 watts, and can deliver 165 watts to juice multiple devices at once. You also get a handy built-in cable that doubles as a carry strap, a retractable cable, and a small display to see the precise percentage of remaining power, charging rate for each port, and battery temperature and health.
My pursuit of the best portable chargers has led me to test hundreds of power banks, but this might be my favorite. This transparent, prism-shaped device is a real looker, but it’s also feature-packed, with a maximum output of 170 watts and a 24,000-mAh capacity, not to mention tough, with an IP66 rating for water resistance. It will fast charge just about any small gadget, from phones to laptops, and the handy display shows battery life as a percentage, time remaining, and the input or output in watts.
The Qi2 wireless charging standard was developed in partnership with Apple and features MagSafe-like magnetic alignment and speedier iPhone charging rates of up to 15 watts. This power bank can also charge other Qi2 devices, like Google's Pixel 10 series, and existing Qi devices (just more slowly). This compact power bank also has a handy kickstand, a two-way USB-C port, and an LED display that shows remaining power and time to charge. You can attach MagSafe iPhones in portrait or landscape orientation, and it works with Apple’s StandBy mode, making it one of the best MagSafe power banks.
Slimmest of the slim, this magnetic power bank will cling to the back of your iPhone and keep the battery topped off. It is just 0.3 inches thick and weighs in at 112 grams, so you'll barely notice it's there. The capacity is 5,000 mAh, so you can expect at least a 50 percent battery boost for most iPhones.
Here's a great pick for frequent flyers who need to keep their phone topped off on the go. Statik’s SmartCharge 5-in-1 comes with slide-on Type C, I, and G plug adapters for travel, a magnetic wireless charger (up to 15 watts), USB-A and USB-C ports, and built-in USB-C and Lightning cables. There’s also a flexible carry loop and a small slide-out stand for your phone to sit on.
